配置主用云平台服务器域名同为ip地址，无dns代理配置，为什么能够连接

cloud-management server domain 1.1.1.1  

本来是正常连接的，    如果undo dns proxy enable，然后把cloud-management server domain这条配置去了，然后发现和对应的服务器断连了

重新把cloud-management server domain 1.1.1.1这条配置加上，但是没加dns那条配置，还是能够重新连接

经测试，把域名当成ip发出去了，相当于在报文对应ip的字段上就填了这个域名，不管有没有dns proxy enable，写成ip就不需要dns
